[Dev] experimentally usable sections turned on

[Alec Flett]

An update: I have added the ability for sections to expand/collapse when 
you double-click on them!

Unfortunately there are some rough edges in our grid code, that 
sometimes seems to prevent the sections from expanding/collapsing - it 
seems to be intermittent - either you can always collapse/expand 
sections, or you can't at all. Double-clicking to edit an item elsewhere 
in the table seems to re-enable section expand/collapse, but I'm not 
sure why.

Anyway, incremental progress is being made. Next up: the ability to turn 
these things off :)
